61 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
62     plugin DLL on Windows systems failed
63 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
64     - optimized the SynchronizedConfig class so it doesn't wait
65     unnecessarily long after an update
66 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
67     events (e.g. to highlight the pressed keys on the virtual keyboard
68     of gigedit)

70 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
71 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

82 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
83 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
84     be switched on by command line option "--stacktrace" (the automatic
85     stacktrace mechanism seems to be broken on most systems at the moment)
86 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
87     a pointer to the launched InstrumentEditor object
88 schoenebeck 1876 - added optional 3rd party user data parameter for following
89     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
90     InstrumentEditor::Launch(),

98 schoenebeck 1601
99 schoenebeck 1599 * audio driver:
100     - removed the nonsense audio channel constraint (which was hard coded to
101     max. 100 audio channels) for most audio drivers
102 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
103     opposed to the LSCP specs
104 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
105     reflected the wrong value

110 iliev 1829 - added (experimental) CoreAudio driver
111 persson 1888 - applied old fixes to the ASIO driver that were included in the
112     previous binary release but accidentally never committed to CVS
113     (fixes #117)
114 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
115     win64)
116 persson 1895 - VST: added support for sample rate and buffer size changes
117     - VST: close editor (Fantasia) when the VST is removed
118 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

126     AudioChannel::CopyTo() methods using GCC vector exensions
127     (if available)
128 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
129     exception when getting parameters from a disconnected device
130 schoenebeck 1599
131 persson 1651 * MIDI driver:
132     - added JACK MIDI driver
133 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
134     want to (mis)use it for some purpose ("fixed" in all current MIDI
135     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
136 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
137 persson 1887 CoreMidi or AU
138 persson 1889 - fixed mingw-w64 compilation error in MME driver
139 persson 1924 - made program change handling in MIDI thread real-time safe by
140     moving the logic to a non-RT thread
141 persson 1951 - fixed minor memory leak in ALSA driver
142 persson 1651
143 schoenebeck 1604 * instruments database:
144 iliev 1603 - avoid time consuming samples scanning when adding instruments
145     to the instruments database
146 iliev 1727 - added support for handling lost files in the instruments database

148     in the instruments database
149     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
150 persson 1908 - work-around for missing fnmatch function on Windows to make
151     instrument database compilable
152 schoenebeck 1930 - added instrument database support on Windows
153     works with both standalone mode and VST plugin.
154     the instruments DB file is located in
155     %USERPROFILE%\.linuxsampler\instruments.db which allows different
156     databases for each windows user
157     if no DB is present it automatically creates the .linuxsampler subdir
158     and then creates an empty DB
159 persson 1943 - fixed recursive import, which was broken on Windows
160 iliev 1603
161 persson 1644 * Gigasampler format engine:
162     - fixed a memory leak that could happen when a channel was deleted
163     while notes were playing
164 persson 1646 - made it possible to load an instrument even if the audio thread
165     isn't running
166 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
167     enough for piano gigs with pedal noise samples
168 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
169     respective FX send MIDI controller was used
170 schoenebeck 1724 - added support for GM global device volume SysEx message
171 schoenebeck 1762 (can be selected at compile time to either apply globally to the
172     whole sampler [default] or only to the sampler channels that are
173     connected to the respective MIDI input port the SysEx message arrived
174     on)
175 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
176     sometimes wrongly killed in the same buffer, causing no sound to
177     be played
178 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
179     which is usally used to switch a part between chromatic sounds and
180     drumkit sounds (as opposed to their common default setting of MIDI
181     part 10 being a drumkit part and all other ones chromatic parts), in
182     LS however one can switch between the first 16 MIDI instrument maps
183     defined for the sampler
184 persson 1764 - made it possible to create multiple sample channels even if the
185     audio thread isn't running
186 persson 1844 - fixed crash when removing channel with active voices (#116)
187 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
188     un-cache the respective sample if it's really not used by any
189     sampler engine anymore
190     - re-cache samples in case they were changed by an instrument editor,
191     e.g. when a sample was added while playing (#82)
192 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
193     same time stamp as the voice's note-on event and occured both in the
194     same audio fragment cycle (fixes bug #112)
195 persson 1858 - added support for the "fine tune" and "pitch bend range"
196     instrument-level gig parameters
197     - fixed minor artifacts in pitch bend handling
198 schoenebeck 1860 - added support for GS Reset SysEx message
199 persson 1862 - allow gig files to use unlimited downward pitch shifting
200     - added a limit check for upward pitch shifting
201 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
202     note was silent
203 persson 1923 - fixed crash happening when a pitch bend event arrived at the
204     same time a new instrument was loading
205 persson 1644
206 schoenebeck 1687 * LSCP server:
207     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
208     react on MIDI data arriving on certain sampler channels (so far only
209     Note-On and Note-Off events are sent via this LSCP event)
210 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
211     react on MIDI data arriving on certain MIDI input devices (so far only
212     Note-On and Note-Off events are sent via this LSCP event)
213 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
214     SET DB_INSTRUMENT FILE_PATH
215 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
216     frontends to send MIDI messages to specific sampler channel
217     - added two additional fields to GET FILE INSTRUMENT INFO command -
218     KEY_BINDINGS and KEYSWITCH_BINDINGS
219 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
220     was incorrect
221 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
222 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
223     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
224     be triggered respectively
225     - added new LSCP command "SET STREAMS" to globally alter the maximum
226     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
227     which will be triggered respectively
228 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
229     a gigedit file dialog is opened)
230 iliev 1848 - close all connections when LSCPServer is deleted
231 iliev 1882 - hard close of all sockets on exit
232 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
233     driver
234 schoenebeck 1687
235 iliev 1761 * Bug fixes:
236     - fixed a crash which occurs when removing a sampler channel waiting
237     to start instrument loading after another channel
238 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
239     instrument loading in progress (bug #113)
240 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
241     instrument with PERSISTENT load mode
242 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
243     - fixed memory leaks when issuing the following LSCP commands:
244     GET AUDIO_OUTPUT_DRIVER INFO
245     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
246     GET MIDI_INPUT_DRIVER INFO
247     GET MIDI_INPUT_DRIVER_PARAMETER INFO
248     - fixed possible compilation error when sqlite is not present
249 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
250 iliev 1847 - fixed crash when changing the audio output device of a sampler
251     channel with loaded instrument and start playing notes
252 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
253 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
254     PowerPC, which probably could cause crashes on that platform
255 persson 1889 - fixed a memory management error which could cause a crash when a
256     plugin was unloaded
257 persson 1896 - bugfix: two private structs had the same name, which could cause
258     problems if the linker chose the wrong constructor
259 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
260     Windows
261 iliev 1761
262    
263 schoenebeck 1560 Version 0.5.1 (6 December 2007)
264 schoenebeck 1454
265     * packaging changes:
266     - added autoconf checks for pthread library
267     - added autoconf check for pthread bug found on certain NPTL-enabled
268     glibc versions (see Gentoo bug report #194076)
269 senoner 1502 - added autoconf checks for MS Windows
270 schoenebeck 1454
271 persson 1455 * general changes:
272     - bugfix: the thread used by an editor plugin didn't die when the
273     editor closed
274 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
275     out all the space. operator--() did not apply size_mask after
276     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
277     order to avoid problems with the _NonVolatileReader functions.
278     - bugfix: Stream.h: added a missing divide by BytesPerSample in
279     GetWriteSpace(). Since this function is currently only used in
280     the stream's qsort() compare function, it didn't trigger any
281     bugs.
282     - Resampler.h, Synthesizer.h: cubic interpolation now works in
283     24bit mode too. Faster method to read 24bit words on little
284     endian machines (x86): replaced 3 byte reads + shifts with a 1
285     unaligned 32bit read and shift
286     - experimental support for MS Windows (MIDI input via MME, AUDIO
287     output via ASIO)
288     - made handling of SIGINT signal (Ctrl-C) a bit more robust
289 iliev 1541 - support for monitoring the total number of active disk streams
290     (new LSCP commands: GET TOTAL_STREAM_COUNT,
291     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
292 persson 1455
293 senoner 1500 * AUDIO driver:
294 persson 1534 - added Windows ASIO low latency audio driver
295 senoner 1500
296 senoner 1485 * MIDI driver:
297 schoenebeck 1495 - added MME Windows MIDI driver
298 senoner 1485
299 schoenebeck 1471 * LSCP server:
300     - added support for Windows style path / filenames, however with
301     forward slash path separators instead of backslash
302     (i.e. "C:/foo/bar.gig")
303 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
304     apostrophes as well
305 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
306     "LIST FILE INSTRUMENTS <file>" and
307     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
308     about an arbitrary instrument file on the system where the sampler is
309     running on
310 schoenebeck 1471
311 schoenebeck 1424 Version 0.5.0 (15 October 2007)
312 schoenebeck 947
313 schoenebeck 1065 * packaging changes:
314 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
315     API header files anymore
316 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
317     the Doxygen API documentation (explicitly listed in Doxyfile.in)
318 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
319     capable to execute our autoconf environment, thus no need anymore
320     to maintain the compile time configuration file (osx/version.h) for
321     OSX manually (patch by Toshi Nagata)
322 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
323     parameters
324 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
325     C++ API header files, all implementation internal global definitions
326     are now in global_private.h
327     - atomic.h is not exposed to the C++ API anymore
328     - no need to include config.h anymore for using LS's API header files
329     - fixed warnings in API doc generation
330 schoenebeck 1065
331 schoenebeck 947 * general changes:
332     - replaced the old, confusing MIDI program change mechanism by a
333     flexible MIDI instrument mapper which allows to map arbitrary
334 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
335 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
336     loaded on the respective channel when such MIDI program change
337     messages arrive, beside that, each entry allows to define a life-time
338     strategy for the instrument, so the user can define whether the
339     instrument should i.e. be permanently loaded (to be able to switch
340     quickly among sounds) or i.e. loaded just on demand when the
341     respective program change arrives (to safe RAM space), as well as a
342     global volume factor for each entry, so the user can adjust the volume
343     dynamic of his mapped instrument collection without having to modify
344 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
345     MIDI instrument maps and assign each sampler channel individually
346     a certain map, so that i.e. separation of normal instruments and
347     drumkits is possible
348 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
349     MIDI instrument maps, MIDI instruments, FX sends, global volume.
350 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
351     due to a constant size RingBuffer FIFO which is now replaced by a
352     dynamic (unlimited) size std::list FIFO
353 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
354     output channels for being processed by external effect processors
355     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
356     controllers
357 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
358 iliev 1130 - Implemented new, improved notification system
359 schoenebeck 1149 - fixed compilation errors regarding OSX
360     (patch by Toshi Nagata)
361 iliev 1161 - implemented instruments database
362 iliev 1345 - added support for escape sequences to the instruments database
363 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
364     within the sampler's process (by using instrument editor plugins),
365     you'll notice the new "Registered instrument editors:" message on
366 schoenebeck 1407 startup, added a new LSCP command:
367     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
368 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
369     given sampler channel, the plugin path can be overridden at compile
370     time with ./configure --enable-plugin-dir=/some/dir
371 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
372     in the sampler's process to safely edit instruments while playing
373     without a crash (hopefully) by either suspending single regions
374     wherever possible or if unavoidable whole engine(s)
375 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
376     policy and priority on thread level, set a minimum stack size for
377     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
378     threads simply inherited properties of starting thread instead of
379     setting their own policy and priority
380 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
381     main process did not wait for the stack trace process to finish
382     its output
383 persson 1248 - fixed some minor memory leaks
384 schoenebeck 1259 - reenabled assembly features support, at the moment only for
385     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
386 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
387     register, to avoid relocations in the text segment at runtime)
388 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
389 schoenebeck 947
390     * MIDI driver:
391     - dispatch bank select (MSB and LSB) messages
392    
393 schoenebeck 1049 * audio driver:
394     - the ALSA audio output driver parameters now reflect the correct
395     parameter value ranges for the respective selected sound card
396     (patch by Till Wimmer, a bit fixed and extended)
397    
398 persson 951 * Gigasampler format engine:
399     - if a filter is used and EG2 finishes before EG1, let the voice
400     die when EG2 has finished (this fixes a problem with clicks and
401     voice starvation for some gigs)
402 persson 1038 - playback is no longer disabled during instrument loading
403     - all notes playing on a channel that changes its instrument keep
404     playing with the old instrument until they get a note off
405     command
406 persson 1039 - EG fix: a release value of zero could cause noises or crash
407 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
408 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
409     above max sustain level, which means that there is a decay phase
410     even if sustain is 100%
411 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
412     noises or crashes
413 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
414 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
415     supplied to the configure script (fixes #46)
416 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
417     instead of a fix value
418 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
419     127 (solo mode) only kill voices if the respective mode really
420     changed
421 persson 951
422 schoenebeck 1244 * LSCP server:
423     - fixed compile time error for old Bison versions
424     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
425 schoenebeck 1245 - parser now supports extended ASCII character set
426     (up to ASCII code 255, i.e. includes now umlauts and accents)
427     - filename arguments in LSCP commands now allow to use escape
428     sequences, that is directly literal as one of: \', \", \\, \n, \r,
429     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
430     code value like \xf2) (fixes bug #24)
431 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
432     least one of their text-based parameters (i.e. name, description):
433     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
434     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
435     "SET DB_INSTRUMENT_DIRECTORY NAME",
436     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
437     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
438     "FIND DB_INSTRUMENT_DIRECTORIES"
439 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
440     occured, the unexpected character and the actually expected, possible
441     character(s), the latter only if less than 5 possibilities)
442 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
443     settings
444 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
445     of strings were treated as being one string containing commas
446     (fixes #57)
447 schoenebeck 1244
448 iliev 959 * Bug fixes:
449     - fixed crash occurring on certain LSCP scripts (Bug 39)
450 persson 1038 - another thread safety fix for lscp "load engine" and "set
451     channel audio output device"
452 iliev 1283 - fixed a crash which occurs when reassigning the same engine
453     on a sampler channel with connected MIDI device
454 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
455     device connected to a sampler channel to number less then or equal
456     to the index of the port to which the sampler channel is connected.
457 iliev 1296 - The previous bindings were not been disconnected when altering
458     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
459     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
460 iliev 1297 - The active stream/voice count statistic was incorrect.
461 iliev 1298 - notification events were not been sent for some sampler
462     channel changes
463 iliev 1305 - added default min and max values to restrict the number of allowed
464     audio output channels and MIDI input ports
465 iliev 1306 - the connection to the PCM interface is now closed when destroying
466     an audio output device
467 schoenebeck 1332 - files with slash in their path or filename could not be loaded
468 iliev 959
469 schoenebeck 1221 * test cases:
470     - updated and fixed (haven't been touched in a while)
471    
472 schoenebeck 937 Version 0.4.0 (24 November 2006)
473 persson 696
474 schoenebeck 697 * packaging changes:
475 capela 868 - changed deprecated copyright attribute to license; added ldconfig
476     to post-(un)install steps; added devel package for liblinuxsampler;
477     to linuxsampler.spec (RPM)
478 schoenebeck 697 - install necessary development header files for allowing 3rd party
479     applications to link against liblinuxsampler
480     - liblinuxsampler's API documentation can be generated with 'make docs'
481     (Doxygen required)
482 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
483     implementation (currently either an integer math solution or a
484     di-harmonic approximation), automatic detection can be overriden
485     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
486     configure script argument though (mandatory for cross-compilation)
487 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
488     provided some on his own (as CXXFLAGS)
489 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
490     messages
491 schoenebeck 852 - added compile time options to allow disabling the various audio and
492     MIDI drivers
493 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
494     (patch by Ebrahim Mayat)
495 schoenebeck 697
496 persson 696 * Gigasampler format engine:
497 schoenebeck 738 - extensive synthesis optimization
498     (reimplementation of EGs and LFO(s), removed synthesis parameter
499     prerendering and the synthesis parameter matrix in general, splitting
500     each audio fragment into subfragments now where each subfragment uses
501 persson 830 constant pitch and filter coefficients. The volume coefficient is
502     linearly interpolated inside a subfragment, unless
503     --disable-interpolate-volume is set.)
504 persson 696 - fine tuning of the EG modulation parameters
505 persson 729 - improved filter cutoff calculation by adding support for the
506     following gig parameters: Cutoff freq (used when no cutoff
507     controller is defined), Control invert, Minimum cutoff, Velocity
508 persson 791 curve and Velocity range. The keyboard tracking now scales
509     cutoff frequency instead of resonance.
510 persson 877 - added support for gig parameter Resonance.
511 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
512 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
513     which can be overridden with --enable-global-attenuation
514 persson 783 - EG fixes: made the length of "attack hold" stage more
515     accurate. Release stage can now start before attack stage
516 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
517     time now has a minimal value to prevent clicks.
518 persson 799 - fixed pitch changes larger than one octave
519 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
520     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
521     all modes can be altered via standard GM messages, that is CC5 for
522     altering portamento time, CC65 for enabling / disabling portamento
523     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
524 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
525     parameter) and crossfade
526 persson 831 - added support for the "attenuation controller threshold" gig
527     parameter
528 persson 832 - added smoothing of volume changes caused by control change
529     messages
530 persson 865 - sample loop parameters are now taken from the DimensionRegion
531     instead of the wave chunk
532     - fixed keyswitching for v3 gigs with a number of keyswitch splits
533     not equal to a power of two
534 persson 877 - reimplementation of the filter algorithm. The new filter is more
535     accurate and supports all gig filter types, including bandreject
536     and lowpass turbo.
537 persson 903 - real support for 24 bit samples - samples are not truncated to
538     16 bits anymore
539     - support for aftertouch (channel pressure, not polyphonic
540     aftertouch)
541 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
542     amplifying from 0)
543 persson 696
544 schoenebeck 711 * LSCP server:
545     - fixed application exit on broken pipe error (fixes bug #20)
546 iliev 793 - fixed the notification messages delay due to lack of
547     network activity (fixes bug #26)
548 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
549     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
550 schoenebeck 711
551 schoenebeck 838 * audio driver:
552     - added aRts audio output driver (by no means RT safe)
553    
554 schoenebeck 775 * MIDI driver:
555     - fixed legacy sysex code which caused dispatching of MIDI SysEx
556     messages several times instead of once
557 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
558     for events (i.e. for offline rendering based MIDI drivers)
559 persson 922 - added checks for bad MIDI data
560 schoenebeck 775
561 schoenebeck 900 * linuxsampler application:
562     - show available sampler engine types on startup
563    
564 schoenebeck 705 * general changes:
565     - support for muting sampler channels and solo mode of the same, two new
566     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
567     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
568     introduced for this, the behavior is the same like on a mixer console
569 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
570     --enable-process-muted-channels which can be used to enable the
571     processing of muted channels.
572 iliev 777 - support for sostenuto pedal
573 iliev 779 - support for monitoring the total number of active voices
574 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
575     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
576 persson 835 - fixed some memory management errors
577 persson 841 - fixed some concurrency problems that could lead to crashes when
578     LSCP commands were executed
579 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
580     sampler channel (fixes bug #36)
581 schoenebeck 705
582 schoenebeck 692 Version 0.3.3 (15 July 2005)
583 schoenebeck 686
584     * packaging changes:
585     - fixed compilation with gcc 4.0
586    
587 schoenebeck 687 * Gigasampler format engine:
588     - LFO preprocessing was performed even though the respective LFO was
589     disabled by the instrument patch (minor efficiency fix)
590 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
591     for volume ramp downs in the same fragment (needed for current voice
592     stealing implementation) then simply inform the user with a warning
593     about possible click sounds and reduce the volume ramp down
594     appropriately instead of cancelling the audio device connection
595 schoenebeck 687
596 schoenebeck 677 Version 0.3.2 (24 June 2005)
597 schoenebeck 609
598     * packaging changes:
599     - updated autotools build files to compile on OS X
600     (conditional compilation of CoreMIDI and MidiShare drivers)
601 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
602     './configure --disable-asm' (definitely not recommended)
603 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
604     - require automake (>= 1.5) for 'make -f Makefile.cvs'
605     (due to 'dist-bzip2' automake option)
606 schoenebeck 649
607     * Gigasampler format engine:
608     - support for the gig parameters for "release velocity response" curves
609     - fine tuning of the EGADSR envelope
610     - volume of release triggered samples now depends on note-on velocity,
611     note length and gig parameter "release trigger decay" instead of
612     note-off velocity.
613 schoenebeck 663 - revised voice stealing
614     (fixes crash and endless loop caused by voice stealing)
615 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
616 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
617     instead of when the respective voice is actually launched
618     (fixes undefined behavior if stolen voices belonged to a key group -
619     this case was followed by a "killed voice survived" error message)
620 schoenebeck 669 - fixed minor issue with null/silence samples
621     (those stole voices even though they don't need a voice at all which
622     resulted in "voice stealing didn't work out" messages)
623 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
624     instrument or audio output device change
625 schoenebeck 654
626 schoenebeck 620 * LSCP server:
627 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
628 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
629 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
630 schoenebeck 609
631 schoenebeck 668 * linuxsampler application:
632     - added command line parameters --lscp-addr and --lscp-port to override
633     default IP address and port of LSCP server
634    
635 schoenebeck 579 Version 0.3.1 (24 May 2005)
636    
637     * initial release
